#429 Anker Soundcore Space A40: $54.99 TWS Amazon $54.99 eBay
Pros: Active noise cancelling, LDAC streaming, IPX4 splash resistance and a claimed 10 hours per charge (50 with the case) make this a well equipped set of true wireless earbuds for the money. In hobbyist measurements the bass and midrange sit close to target, with the low mids within half a decibel, so voices sound natural rather than boomy. Its taste profile matches listeners who prefer a warm or neutral balance over heavy bass.
Cons: Sub-bass falls 6 dB below target by 42 Hz and is 7.5 dB down at 30 Hz, so deep synth bass and movie rumble go missing. A dip of 9.9 dB near 11.9 kHz and an air band almost 7 dB low dull cymbals and the sense of space. The Anker Soundcore Liberty 4 NC rates slightly higher for buyers who want more bass.
